A purification device

Abstract

This utility model discloses a purification device, including a roller, a drive assembly, a first purification module, and a second purification module. The roller has a first mounting cavity and a second mounting cavity circumferentially. The first purification module is fixed in the first mounting cavity, and the second purification module is fixed in the second mounting cavity. The drive assembly is connected to the roller. The initial position of the first mounting cavity corresponds to the purification work area, and the initial position of the second mounting cavity corresponds to the cleaning work area. When the first purification module adsorbs a large amount of pet hair in the purification work area, the drive assembly drives the roller to rotate, causing the first purification module to move to the cleaning work area and disengage from the air duct. At this time, the pet hair cleaning program is started. Simultaneously, the second purification module moves into the purification work area to continue adsorbing pet hair floating in the air, ensuring zero interruption in the capture and processing of pet hair. This dual-zone rotation mechanism solves the pain point of traditional air purifiers requiring shutdown for maintenance due to pet hair blockage.

Description

Technical Field

[0001] This utility model belongs to the field of air purifiers, and specifically relates to an air purification device. Background Technology

[0002] With the continued rise in household pet ownership, the pollution problem caused by pet hair in indoor environments is becoming increasingly prominent. Existing air purification equipment mainly relies on fiber filters to intercept hair pollutants, but this passive filtration method has inherent flaws: when a certain amount of hair accumulates on the filter surface, the airflow channels quickly become blocked, leading to a surge in air resistance and an exponential decline in purification efficiency. Users are forced to frequently interrupt equipment operation to manually clean or replace the filters, resulting in high maintenance costs and a significant reduction in the effective operating time of the equipment. While self-cleaning filter technology exists in the current market, it still requires manual disassembly and rinsing or relies on complex water washing systems, failing to achieve maintenance-free closed-loop cleaning during continuous purification. The core of these technological bottlenecks lies in the inability of a single functional module to simultaneously undertake the dual functions of efficient purification and automatic maintenance, urgently requiring structural innovation to resolve the conflict between the working and maintenance states of the purification unit. Utility Model Content

[0003] In view of this, the present invention provides a purification device that solves the contradiction that the functional modules of traditional purification devices cannot take into account both working and maintenance status during continuous purification, and breaks through the technical bottleneck that single-module purifiers require manual cleaning after shutdown.

[0004] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides a purification device comprising a roller, a drive assembly, a first purification module, and a second purification module. The roller has a first mounting cavity and a second mounting cavity in its circumferential direction. The first purification module is fixed to the first mounting cavity, and the second purification module is fixed to the second mounting cavity. The drive assembly is connected to the roller. The initial position of the first mounting cavity corresponds to a purification work area, and the initial position of the second mounting cavity corresponds to a cleaning work area. When the dust accumulation in the first purification module reaches a threshold, the drive assembly drives the roller to rotate, causing the first mounting cavity to move to the cleaning work area, and simultaneously, the second mounting cavity moves to the purification work area.

[0005] In some embodiments, the drive assembly includes a drive motor, a gear, and a gear ring. The gear ring is disposed on the outer periphery of the drum. The output end of the drive motor is connected to the gear. The gear meshes with the gear ring to form a transmission pair to drive the drum to rotate.

[0006] In some embodiments, the cleaning work area is provided with a dust removal component, which includes an adsorption interface and a collection box. One end of the adsorption interface is disposed facing the surface of the first or second mounting cavity of the cleaning work area, and the other end of the adsorption interface is connected to the collection box, which is provided with a filter screen.

[0007] In some embodiments, the collection box is a detachable structure; the collection box is equipped with a hair filter inside.

[0008] In some embodiments, both the first purification module and the second purification module include a support, a cover plate, a filter screen, and alternatingly stacked discharge electrodes and collecting electrodes. The cover plate is disposed on one side of the support, and both the cover plate and the other side of the support are provided with slots. The discharge electrodes and collecting electrodes are stacked at a set interval and fixed by the slots. The collecting electrode is grounded, and the discharge electrode includes a flat plate enhancement portion and a tip discharge portion.

[0009] In some embodiments, the stacking order of the discharge electrode and the collector electrode is: collector electrode, plate reinforcement portion, collector electrode, tip discharge portion, collector electrode.

[0010] In some embodiments, the purification device further includes a detection unit, which includes an infrared sensor disposed on the air outlet side of the purification work area, for monitoring the dust and lint accumulation on the filter and triggering a rotation command.

[0011] In some embodiments, when the infrared sensor detects a value exceeding a set threshold, the drive component automatically initiates a rotation program.

[0012] In some embodiments, the purification device further includes a housing, an air inlet channel at the top of the housing, and the roller below it. The inner cavity of the roller forms an active platform that allows pets to enter, and the air outlet of the air inlet channel communicates with the inner cavity of the roller.

[0013] In some embodiments, the first mounting cavity and the second mounting cavity are symmetrically distributed about the central axis of the drum, and the first purification module and the second purification module are interchangeable identical structures.

[0014] Compared with the prior art, the purification device of this utility model has at least the following beneficial effects:

[0015] The purification device provided by this utility model includes a roller, a drive assembly, a first purification module, and a second purification module. The roller has a first mounting cavity and a second mounting cavity in its circumferential direction. The first purification module is fixed in the first mounting cavity, and the second purification module is fixed in the second mounting cavity. The drive assembly is connected to the roller. The initial position of the first mounting cavity corresponds to the purification operation area, and the initial position of the second mounting cavity corresponds to the cleaning operation area. When the dust accumulation in the first purification module reaches a threshold, the drive assembly drives the roller to rotate, causing the first mounting cavity to move to the cleaning operation area, and simultaneously the second mounting cavity moves to the purification operation area.

[0016] Addressing the technical challenge of pet hair clogging the purification module: In this embodiment, when the first purification module accumulates a large amount of pet hair in the purification work area, causing an increase in air resistance, the drive component drives the roller to rotate, moving the first purification module to the cleaning work area and removing it from the air duct. At this point, the pet hair cleaning program is initiated. Simultaneously, the second purification module moves into the purification work area to continue absorbing pet hair floating in the air, ensuring uninterrupted capture and processing of pet hair. This dual-zone rotation mechanism solves the pain point of traditional air purifiers requiring shutdown for maintenance due to pet hair clogging, eliminating the burden of manual cleaning and significantly improving the continuous processing capacity for high-volume pet hair pollution.

[0034] This embodiment provides a purification device, such as Figures 1-10 As shown, the purification device includes a roller 1, a drive assembly 2, a first purification module 3, and a second purification module 4. The roller 1 has a first mounting cavity 11 and a second mounting cavity 12 in its circumferential direction. The first purification module 3 is fixed to the first mounting cavity 11, and the second purification module 4 is fixed to the second mounting cavity 12. The drive assembly 2 is connected to the roller 1. The initial position of the first mounting cavity 11 corresponds to the purification operation area, and the initial position of the second mounting cavity 12 corresponds to the cleaning operation area. When the dust accumulation in the first purification module 3 reaches a threshold, the drive assembly 2 drives the roller 1 to rotate, causing the first mounting cavity 11 to move to the cleaning operation area, and at the same time, the second mounting cavity 12 moves to the purification operation area.

[0035] The circumferential surface of the roller 1 is provided with a first mounting cavity 11 and a second mounting cavity 12, which are respectively physically embedded to fix the first purification module 3 and the second purification module 4; the drive assembly 2 is directly connected to the outer surface of the roller 1 through a mechanical transmission interface. The first mounting cavity 11 initially faces the air inlet of the air duct to form a purification operation area, and the second mounting cavity 12 initially faces away from the air inlet to correspond to the cleaning operation area. All components are rigidly connected: the shaft of the drive assembly 2 is linked to the roller 1, and the two mounting cavities are distributed at intervals on the surface of the roller 1 to achieve position interchangeability. The purification modules are completely embedded in the mounting cavities and cannot be moved.

[0036] The roller 1 carries two purification modules and achieves workstation switching through rotation; the drive component 2 provides rotational power; the first mounting cavity 11 is used to fix the first purification module 3 and guide it to capture pet hair in the purification work area; the second mounting cavity 12 is used to fix the second purification module 4 and guide it to prepare for rotation in the cleaning work area; the first purification module 3 captures pet hair and dust from the air or the pet in the purification work area through electrostatic adsorption; the second purification module 4, as a backup module, immediately takes over the pet hair adsorption task after rotation. All components work together to form a dual-state circulation system of purification and standby.

[0037] When the device is started, the first purification module 3 uses high-voltage electrostatic adsorption to attract pet hair in the purification work area; the second purification module 4 is on standby in the cleaning work area. When pet hair accumulates to a threshold on the surface of the first purification module 3, the drive component 2 drives the roller 1 to rotate, causing the first mounting cavity 11 to move the first purification module 3 into the cleaning work area, triggering the automatic hair removal program. At the same time, the second mounting cavity 12 moves the second purification module 4 into the purification work area and is powered on to continue adsorbing pet hair. The entire process achieves continuous capture and switching maintenance of pet hair without interruption.

[0038] Addressing the technical challenge of pet hair clogging the purification module: In this embodiment, when the first purification module 3 absorbs a large amount of pet hair in the purification work area, causing an increase in air resistance, the drive component 2 drives the roller 1 to rotate, moving the first purification module 3 to the cleaning work area and removing it from the air duct. At this time, the pet hair cleaning program is initiated. Simultaneously, the second purification module 4 moves into the purification work area to continue absorbing pet hair floating in the air, ensuring zero interruption in the capture and processing of pet hair. This dual-zone rotation mechanism solves the pain point of traditional air purifiers requiring shutdown for maintenance due to pet hair clogging, eliminating the burden of manual cleaning and significantly improving the continuous processing capacity for high-load pet hair pollution.

[0039] In a specific embodiment, such as Figure 6 and Figure 8 As shown, the drive assembly 2 includes a drive motor 21, a gear 22, and a gear ring 23. The gear ring 23 is disposed on the outer periphery of the drum 1. The output end of the drive motor 21 is connected to the gear 22. The gear 22 meshes with the gear ring 23 to form a transmission pair to drive the drum 1 to rotate.

[0040] The motor shaft of drive motor 21 is rigidly connected to the mounting shaft of gear 22 via a keyway or coupling, ensuring that the two are coaxially fixed and have no relative displacement. The tooth surface of gear 22 and the tooth groove of gear ring 23 form a full-width meshing state. Gear ring 23 is completely covered and fixed to the outer circumferential surface of the cylinder of roller 1 by welding or bolt fastening. The output shaft of drive motor 21 drives gear 22 to rotate. The teeth of gear 22 push the tooth groove of gear ring 23 to produce circumferential motion. Because gear ring 23 is physically fixed to roller 1, it forces roller 1 to rotate synchronously.

[0041] The core function of the drive motor 21 is to convert electrical energy into mechanical energy, output controllable rotational power, and set the rotation direction and angle. The key function of the gear 22 is to receive the input torque of the drive motor 21 and amplify the output force. Through its small tooth structure and the large tooth structure of the gear ring 23, it forms a speed reduction and torque amplification mechanism. More specifically, during the meshing process of the teeth of the gear 22 and the tooth groove of the gear ring 23, high-speed low torque is converted into low-speed high torque output. The core function of the gear ring 23 is to serve as a power conversion interface, converting the tangential force of the gear 22 into the rotational driving force of the roller 1. At the same time, because the contact area between the gear ring 23 and the roller 1 is large, it evenly bears the force, thereby ensuring the overall force balance of the roller 1 and avoiding eccentric vibration or local deformation.

[0042] When the control system sends a rotation command, the drive motor 21 is powered on and starts, driving the gear 22 to rotate in the set direction. The teeth of the gear 22 are sequentially engaged with the corresponding slots of the gear ring 23 and a radial thrust is applied, forcing the gear ring 23 to undergo angular displacement. As the gear 22 continues to rotate, the meshing force is transmitted to the drum 1 in the full circumference through the gear ring 23, thereby driving the drum 1 to rotate precisely around the axis. More specifically, the large diameter of the gear ring 23 amplifies the small rotation angle of the gear 22 into a large angular displacement of the drum 1, achieving the energy-saving effect of driving the rotation of a large component with a small stroke. The final effect is that the drum 1 completes the fixed angle switching (such as 180-degree station conversion) in a zero-slip state. During the rotation, the stable meshing depth of the gear 22 and the gear ring 23 ensures that the angle error is lower than the design threshold. More specifically, the self-locking function is achieved through the tooth number matching relationship to prevent reverse rotation.

[0043] In a specific embodiment, such as Figures 5-7 As shown, the cleaning work area is equipped with a dust removal component 5, which includes an adsorption interface 51 and a collection box 52. One end of the adsorption interface 51 is disposed facing the surface of the first mounting cavity 11 or the second mounting cavity 12 of the cleaning work area, and the other end of the adsorption interface 51 is connected to the collection box 52. A filter screen is disposed inside the collection box 52.

[0044] One end of the adsorption interface 51 faces the surface of the mounting cavity (first mounting cavity 11 or second mounting cavity 12) in the cleaning operation area, and the distance between the two is constant to cover the surface area of ​​the purification module; the other end of the adsorption interface 51 is rigidly connected to the inlet of the collection box 52 through a pipe to form a sealed channel; more specifically, the collection box 52 is fixed to the equipment base through a slide groove, and its inlet axis is coaxially aligned with the outlet axis of the adsorption interface 51; when the first mounting cavity 11 or the second mounting cavity 12 is driven to the cleaning operation area, the purification module (first purification module 3 or second purification module 4) covering its surface is completely exposed directly below the suction port of the adsorption interface 51, forming a physical spatial relationship.

[0045] The core function of the adsorption interface 51 is to generate negative pressure adsorption force on the surface of the purification module (first purification module 3 or second purification module 4) moved to the cleaning operation area, and to peel off and suck up the pet hair and dust attached to the surface. The function of the collection box 52 is to intercept the dirty particles transported by the adsorption interface 51 through the internal filter screen. More specifically, the mesh structure of its filter screen directly traps large particulate pollutants such as pet hair, allowing the cleaning airflow to pass through and store the pollutants in the box, thus achieving dirt separation and centralized collection.

[0046] When the dust-accumulated purification module rotates with the mounting cavity to the cleaning work area, the adsorption interface 51 immediately activates negative pressure adsorption: its suction port generates a high-speed airflow that vertically washes the surface of the purification module, powerfully adsorbing the pet hair clogging the filter media; the detached hair is carried by the airflow through the adsorption interface 51 channel into the collection box 52, where it is intercepted by the internal filter and stored in the box; this synergistic work thoroughly removes the hair accumulation on the surface of the purification module, restoring its adsorption capacity; more specifically, the entire dust removal process requires no module disassembly or manual intervention, and secondary dust pollution is avoided by the physical isolation of the collection box 52. The ultimate effect is to achieve online automated cleaning of the purification module, ensuring its continuous adsorption efficiency of pet hair and maintaining the overall purification stability of the system.

[0047] In a specific embodiment, the collection box 52 has a detachable structure; the collection box 52 is equipped with a hair filter screen inside.

[0048] The detachable structure of the collection box 52 is specifically manifested in its physical separability from the main body of the device via a sliding rail or snap-fit ​​assembly, allowing users to directly apply external force to completely remove it from the device. Simultaneously, the hair filter integrated within the collection box 52 is fixed within the internal cavity of the box, its mesh size specifically designed to intercept pet hair. More specifically, the hair filter covers the entire cross-section of the airflow channel and is positioned at a specific distance from the inlet of the collection box 52. This design produces multiple benefits: First, when the hair intercepted by the hair filter accumulates to the point where it needs cleaning, the detachable structure allows users to quickly separate the collection box 52 for manual emptying without tools or complex operations; second, the direct interception of the air-solid mixture by the hair filter ensures that pet hair is concentrated and retained within the collection box 52, preventing hair from escaping to the rear of the device and causing secondary pollution; third, the overall structure, through physical isolation, ensures that the pollution cleaning process is completed entirely within the collection box 52, preventing users from contacting contaminants and ensuring hygiene and safety; ultimately, it achieves a simultaneous improvement in the maintenance efficiency and hygiene of the purification system.

[0049] In a specific embodiment, such as Figures 2-4As shown, both the first purification module 3 and the second purification module 4 include a support 43, a cover plate 44, a filter screen, and alternatingly stacked discharge electrodes 41 and collecting electrodes 42. The cover plate 44 is disposed on one side of the support 43, and both the cover plate 44 and the support 43 are provided with slots 45. The discharge electrodes 41 and collecting electrodes 42 are stacked at a set interval and fixed through the slots 45. The collecting electrode 42 is grounded, and the discharge electrode 41 includes a flat plate reinforcement part 411 and a tip discharge part 412.

[0050] The support frame 43 serves as the core support skeleton, with continuous arrays of slots 45 on both ends. The cover plate 44 is tightly covered on one end of the support frame 43 by bolts or buckles, and together with the support frame 43, they form a rectangular frame structure. More specifically, the filter screen is evenly laid in the cavity inside the frame of the support frame 43. The discharge electrode 41 and the collecting electrode 42 are stacked in an alternating order of discharge electrode 41, collecting electrode 42, and discharge electrode 41. The two ends of each layer of electrodes are vertically embedded in the corresponding slots 45 of the support frame 43 and the cover plate 44. The limiting effect of the slots 45 keeps all electrodes parallel and spaced at a set interval. The flat plate reinforcement part 411 of the discharge electrode 41 is mechanically fixed by inserting into the slot 45, and the tip discharge part 412 is suspended at the center of the gap between the two electrodes.

[0051] The bracket 43 provides a rigid support frame for the entire purification module, ensuring the overall stability of the electrode stacked structure. The cover plate 44 closes the open side of the bracket 43 to form a semi-closed cavity, and at the same time, it fixes the electrodes through its slot 45. The filter screen physically intercepts residual particles in the airflow that have not been adsorbed by the electrodes. The key function of the slot 45 is to forcibly constrain the spatial position of the discharge electrode 41 and the collecting electrode 42 through precisely machined positioning slots, ensuring that the distance between adjacent electrodes remains constant. The core function of the discharge electrode 41 is to generate high-concentration ions through the tip discharge part 412 to charge the particles, and its flat plate reinforcement part 411 helps to enhance the electric field distribution. The collecting electrode 42 uses its grounding characteristics to adsorb charged particles to complete the purification.

[0052] During operation, the dust-laden airflow first flows through the alternating layers of discharge electrodes 41 and collecting electrodes 42: the discharge tip 412 of the discharge electrode 41 generates corona discharge through a high voltage, causing the pet hair in the airflow to become positively charged; the charged hair is then strongly adsorbed and captured by the grounded collecting electrode 42; more specifically, the micro-dust not adsorbed by the electrodes continues to pass through the filter screen and is intercepted a second time; the slot 45 maintains the precise spacing between the electrodes, ensuring the ionization-collection process continues efficiently and avoiding electric field distortion caused by electrode displacement; the cavity formed by the bracket 43 and the cover plate 44 constrains the airflow to pass evenly through all functional layers. This embodiment significantly improves the pet hair removal rate; at the same time, the modular design of the slot 45 makes the electrodes easy to install and remove, facilitating maintenance and replacement.

[0053] In a specific embodiment, the stacking order of the discharge electrode 41 and the collector electrode 42 is as follows: collector electrode 42, plate reinforcement portion 411, collector electrode 42, tip discharge portion 412, collector electrode 42.

[0054] The airflow first contacts the first collecting electrode 42 fixed in the slot 45; immediately following it is the flat plate reinforcement 411 of the discharge electrode 41 (which serves as the base of the discharge electrode 41), with its two side edges embedded in the slot 45; a second collecting electrode 42 is disposed behind the flat plate reinforcement 411; subsequently, the tip discharge portion 412 of the discharge electrode 41 (a needle-like structure extending from the flat plate reinforcement 411) is embedded in the slot 45; and a third collecting electrode 42 is disposed at the end. More specifically, all components are arranged in parallel in strict accordance with the sequence of "collecting electrode 42 - flat plate reinforcement 411 - collecting electrode 42 - tip discharge portion 412 - collecting electrode 42", with adjacent components maintaining a set distance without physical contact through the slots 45, and the tip of the tip discharge portion 412 pointing towards the plate surface of the adjacent collecting electrode 42.

[0055] The first-layer collecting electrode 42 pre-adsorbs large particulate pollutants already charged in the airflow; the core function of the flat plate reinforcement section 411 is to provide mechanical support and expand the electric field coverage; the second-layer collecting electrode 42 captures charged particles ionized by the flat plate reinforcement section 411; the core function of the tip discharge section 412 is to generate a strong electric field to concentrate ionization and charge residual particles; the final collecting electrode 42 is responsible for the final adsorption of residual charged particles. Furthermore, this sequence design places a collecting electrode 42 behind each key functional layer, forming a progressive purification mechanism that alternately strengthens discharge and collection.

[0056] During operation, the dust-laden airflow passes through a five-layer functional structure: the first-layer collecting electrode 42 directly adsorbs pre-charged pet hair using its grounding properties; subsequently, the airflow passes through the uniform electric field region extended by the flat plate reinforcement section 411, where tiny particles are initially charged and captured by the following second-layer collecting electrode 42; then, the tip discharge section 412 generates a high-density ion storm through its needle tip, forcibly charging the ultrafine particles that have penetrated the previous stage; finally, the last-layer collecting electrode 42 completely adsorbs these charged particles. This structure achieves full-scale coverage removal of pet hair through a four-stage synergistic purification process of "pre-filtration - slow-release ionization - deep ionization - final collection".

[0057] In a specific embodiment, such as Figure 10 As shown, the purification device also includes a detection unit 6, which includes an infrared sensor located on the air outlet side of the purification operation area, used to monitor the dust and lint accumulation on the filter and trigger a rotation command.

[0058] The detection unit 6 is located on the airflow outlet side of the purification operation area of ​​the purification device. Its core component is an infrared sensor, which continuously monitors the filter surface covered by the purification operation area module in a fixed manner. By analyzing changes in the infrared reflection signal, it determines the degree of dust or hair accumulation on the filter. When the detected accumulation exceeds a preset threshold, the detection unit 6 generates an electrical signal command to automatically trigger the rotation drive system to rotate and switch the installation cavity. More specifically, this feature enables fully automatic intelligent perception and response to the purification system status. The direct monitoring of dust and hair accumulation on the filter by the infrared sensor avoids the tediousness of manual periodic inspections, while the triggered rotation command can promptly move the dust-accumulating module into the cleaning operation area to perform dust removal, preventing filter clogging and subsequent decrease in purification efficiency.

[0059] In a specific embodiment, when the infrared sensor detects a value exceeding a set threshold, the drive component 2 automatically starts the rotation program.

[0060] The infrared sensor in detection unit 6 monitors the reflected signal value of the filter surface in real time on the air outlet side of the clean operation area. When the value continuously exceeds the system's set threshold, it automatically sends a start signal to drive component 2, which immediately activates the rotation displacement program of the mounting cavity. Once the infrared sensor detects that the degree of dust and hair accumulation has reached the preset risk level, the drive component 2's zero-delay response can forcibly trigger the rotation and switching of the purification module, promptly moving the clogged module into the clean operation area for cleaning, preventing the decline in purification efficiency caused by filter blockage; at the same time, it eliminates the risk of lag in manual monitoring, ensuring that the equipment automatically maintains optimal purification performance during continuous operation, and improving the overall system's reliability and long-term stability.

[0061] In a specific embodiment, such as Figure 5 and Figure 6 As shown, the purification device also includes a housing 7, with an air inlet channel 71 at the top and the roller 1 inside. The inner cavity of the roller 1 forms an active platform 72 that allows pets to enter, and the air outlet of the air inlet channel 71 communicates with the inner cavity of the roller 1. One end of the housing 7 has a baffle 8 with an opening for pets to enter and exit.

[0062] The overall structure of the outer shell 7 covers the outside of the device, and a circular air inlet channel 71 is opened on its top. The bottom opening of the air inlet channel 71 directly connects to the cavity of the roller 1 below, so that the central area of ​​the air inlet channel 71 actually extends into the movable space inside the roller 1. More specifically, the roller 1 is driven to rotate by the drive component 2, and its inner cavity forms an active platform that can accommodate pets. The air inlet channel 71 serves as an airflow inlet and is connected to the active platform 72.

[0063] The outer shell 7 provides a protective and support frame for the entire machine; the air inlet channel 71 has a dual function: it guides the external airflow vertically into the inner cavity of the roller 1, and its circular opening forms a channel for pets to enter and exit the activity platform; the core function of the activity platform is to provide pets with an accessible play and rest area, in which the pet's skin and hair are absorbed by the downward airflow in real time.

[0064] During operation, airflow is continuously injected into the inner cavity of the roller 1 through the air inlet channel 71 to form a negative pressure environment. When the pet rests or plays on the activity platform inside the roller 1, the loose hair on its body surface is forcibly adsorbed by the airflow. At the same time, the drive component 2 drives the roller 1 to rotate slowly, which not only enhances the force of the airflow on the pet's hair, but also gives the pet a dynamic interactive experience. Ultimately, it optimizes the efficiency of loose hair removal and enhances the fun of use.

[0065] In a specific embodiment, the first mounting cavity 11 and the second mounting cavity 12 are symmetrically distributed about the central axis of the roller 1, and the first purification module 3 and the second purification module 4 are interchangeable and identical structures.

[0066] The first mounting cavity 11 and the second mounting cavity 12 are symmetrically distributed at 180° with respect to the rotation center axis of the roller 1. Furthermore, the first purification module 3 and the second purification module 4 adopt identical structures, possessing complete interchangeability in physical dimensions and interface functions. More specifically, the core effects of this layout are reflected in three aspects: First, the symmetrical distribution ensures uniform mass distribution during the rotation of the roller 1, eliminating vibration and noise caused by eccentric rotation and ensuring the mechanical stability of the equipment operation. Second, the complete interchangeability of the purification modules significantly reduces the difficulty of user maintenance. When a module's filter element reaches the end of its service life, it can be directly replaced without distinguishing between models, and idle modules can be disassembled, cleaned, or replaced at any time. Furthermore, the symmetrical layout and interchangeability of the dual modules create a synergistic effect, ensuring functional consistency between the two purification work areas when the drive component 2 performs rotational switching, thereby maintaining the stability of airflow parameters and adsorption effect during continuous purification, ultimately achieving high reliability and low maintenance costs throughout the equipment's entire lifecycle.

[0067] The working process of the purification device provided in this embodiment is described in detail below:

[0068] Initially, external air is drawn in through the air inlet channel 71 at the top of the outer casing 7, and vertically injected into the movable platform 72 area formed by the inner cavity of the roller 1 through the air outlet of the air inlet channel 71. At this time, pets can freely enter the movable platform 72 to play or rest. The negative pressure of the downward suction airflow adsorbs the pet's body hair in real time, and the airflow further carries the hair into the working area. More specifically, when the airflow passes through the inside of the roller 1, it is intercepted and filtered by the first purification module 3 or the second purification module 4 installed in the current purification working area. The purified air is then discharged from the equipment to achieve the cleaning function. At the same time, the infrared sensor in the detection unit 6 monitors the filter reflection signal value on the air outlet side of the purification working area in real time. When the detected dust accumulation signal value continuously exceeds the preset threshold, the detection unit 6 immediately sends a start signal to the drive component 2. Furthermore, the drive component 2 activates without delay upon receiving the signal, causing the roller 1 to rotate rapidly by approximately 180°. The symmetrical distribution design of the first mounting cavity 11 and the second mounting cavity 12 ensures a smooth and vibration-free rotation process, moving the originally clogged purification module into the cleaning operation area and switching to the standby purification module. This cyclic switching mechanism enables real-time replacement of the purification module, ensuring efficient hair adsorption while eliminating the need for manual intervention. Ultimately, this achieves automatic maintenance during continuous equipment operation, stable improvement in purification efficiency, and long-term assurance of overall reliability.

[0069] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0070] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
